IMPROVEMENT IN CARRIAGE-AXLES.

The Schedule referred to in these Letters Patent and. making part of thesame.

To all whom it may concern:

Be it known that I, GEORGE A. LLOYD, of the city and county of SanFrancisco, State of California, have invented certain new and usefulImprovements in Axles and Boxes for Vehicles, and I do hereby declarethat the following is a' full, clear, and exact description of the same,reference being bad to the accompanying drawings and to the lettersmarked thereon.

My invention relates to the combination and arrangement of a double box,nut, and washer with the axle, in such a manner as to secure anautomatic supply of the lubricating substance employed to all thewearing surfaces for a greater length of time, without attention orrenewal of the supply of said lubricating substance, than'has beenhitherto possible in the use of similar devices, and also to attain amaximum of securityagainst the collection of grit or dust between thesurface and the sticking fast of the boxes to the ax e.

The object of .my invention is to provide a combined box and axle forvehicles that can be run for a maximum of distance or length of timewithout attention, and with a minimum of wear and liability toderangement.

To enable others skilled in the art or science to which it most nearlyappertains to make and use my invention, I will proceed to describefully its construction and operation.

In the drawings Figure 1, sheet 1, is an elevation representing thearrangement complete.

Figure 2, sheet 1, is a longitudinal section of the same.

Figure 3, sheet 1,'is an end view from the left of der a.

To obviate this difficulty the axle A is much enlarged at that part,and-the shoulder a is forged in one piece with the axle, and the wholefinished or burned as shown in fig. 2, sheet 1.

Figure 4, sheet 1, is an end view from the right of The inner box B andouter box 0 are of such configuration as to correspond with and have abearing upon the exterior surface of the enlarged part of the axle andupon the outer surface of the part forming the shoulder a, and upon eachother, and when in position recesses or spaces are formed for collars orwashers E, F, and G, and recesses 01'' spaces b b, for v retaining asupply of the lubricating substance. 7

The inner box B is provided with perthrations recesses, and longitudinalgrooves, for the same purpose, but differs from all others in having theenlarged or expanded parts a 0, bearing upon and effectually lubricatingthe corresponding parts of the outer box 0 and the axle A.

The form of the outer box also admits of having feathers, d d, as shown,in such, position as to be more easily fitted to, and affording greatersecurity against turning in the hub, than is usual in boxes of ordinaryconstruction.

By this construction the recesses and grooves in box. B gather upandcollect any dust or grit that may find its way to the bearing surface.

The washers E F G may be made of leather or some other suitable elasticsubstance, and serve the double purpose of preventing noise and also ofpreventing the entrance of grit or the escape of the lubricatingsubstance to or from the wearing surfaces.

The nut D is firmly screwed against the shoulder e, and the washers E 1G are made of just sufiicient thickness to be slightly compressed by thesaid nut, and said washers must.be occasionally renewed, as they becomeworn.

When in operation, the inner box B will usually revolve with the wheelor outer box 0; but if, from the entrance of grit or any other cause,undue or excessive friction should arise between the box B and the axle,the box B would adhere to the axle, and the wheel and box 0 wouldrevolve around both, and the wearing be transferred to the outer surfaceof box B and inner surface of box 0..

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

In combination with the outer box 0 and axle A, having an enlargementand shoulder a, the inner box B, having the enlarged or expanded parts 00', bearing upon and lubricating the outer box 0 and axle A, and formingrecesses b b, substantially as described and specified.

In testimony whereof I have hereunto set my hand and seal.
